in an advanced state of growth, the chief difference between 

 the description of his plant and that of S. and W. being the 

 lobate upper segment of the calyx of the former. I find, in one 

 or two TTtricularice of this group, that this lobe of the calyx, ori- 

 ginally entire, or at most retuse or emarginate, often splits more 

 or less towards maturity, thus presenting quite a bilobate form. 

 The appendaged seeds are very remarkable ; but in this respect 

 they differ from other Himalayan species of the same series 

 (including the well-known U. orhiculata of Wallich) merely in the 

 form of the produced epidermal cells of the testa, which, as noted 

 by Dr. Wight, in this latter species are glochidiate or capitate, 

 while in the Kumaon plant they are elongated hairs from the 

 extremities. 



The Sikkim and Khasia collections of Dr. Hooker include two 

 or three new species belonging to the same group with these 

 plants ; but I have not been fortunate enough in every case to 

 meet with matured seeds, the further examination of which is 

 very desirable. These singular Utricularias constitute a most 

 interesting section of the genus, characterized by small stature, 

 orbiculate, reniform, or obovate-spathulate leaves, very unequal 

 calyx-lobes, the lobed, more or less plane, lip of the corolla, and 

 (so far as sufficiently matured specimens enable me to speak) the 

 appendaged seeds ; perhaps, too, the dehiscence of the capsule, 

 and the ultimately more or less reflex^ed inferior lobe of the calyx, 

 may be common to them. Although these characters confer a 

 striking individuality, yet I do not discover that the species pre- 

 senting them are entitled to a rank superior to that of a sub- 

 genus. They are, too, so essentially TTtricularice, that by separating 

 them we should open a door yet more widely to a destruction of 

 the genus as interpreted in books — already, indeed, impending 

 from the separation, by some writers, of certain South American 

 forms. It is perhaps possible that a carefully conducted series of 

 observations upon the embryo and sti'ucture of the seed may lead 

 to a different conclusion ; but until such observations are forth- 

 coming, the more correct course is undoubtedly to retain them as 

 a section of the genus. Dr. Wight, in his valuable * Icones ' 

 (vol. iv.), figures and describes twenty-three species. Some of 

 these, in most cases identified in his herbarium, after examination 

 and comparison with other series, I have thought it quite im- 

 possible to maintain, and have accordingly reduced them. Dr. 

 Wight particularly observed the characters afforded by the surface 

 and form of the seed in certain species, resting, in some cases,
